External Function Call

Classic Servoy
1

Hi,
I’m quite new to using Web Client, but have created a mobile (iOS) UI for my Servoy solution to integrate with a bar code scanner module that attaches to a iPod Touch and allows as laser scanning of bar code data directly into Servoy fields on web client forms.
I have been using an app called iCody for this, but was also looking at another app called ‘SwipeTrack’ (ST)
ST has a web API, that I assume (I am no expert on web page design etc.) causes a JavaScript function event to happen when someone presses the hardware scan button on the external device, allowing more automation of capturing the bar code (even hiding the field it goes into)
Here is what they had on their web page

function onScanAppBarCodeData(bar,t)
		{
			//'bar' is the retrieved Barcode
			document.getElementById('barcode').value = bar;
			
			//'t' is the type of barcode (number code)
			document.getElementById('type').value = t;
			
			return true;
		}

Can I in Servoy add this function to my form methods, replacing the ‘document.getElement…’ bits by either ‘element…=’ or ‘myfield=’ and that the function will be fired by the iOS app??
Thanks
Rafi

No, but using the Webclient Utils plugin you can trigger a servoy method and get the scanned value. Have a look at the docs on ServoyForge and say thanks to Patrick Talbot for this great plugin!
